A. c-b-e-d-a B. b-c-d-e-a C. d-e-c-b-a D. e-b-d-c-a Question 17: a. Many families enjoy living in tall buildings because they can walk to schools, shops, and parks without using cars or buses. b. Cities are becoming very crowded, so architects are building taller buildings where people can live, work, and play in the same place. c. When cities grow up instead of out, more green spaces can remain around the city, and people can enjoy nature even though they live in big urban areas. d. In Singapore and Shanghai, new "vertical forests" have many trees and plants on each floor, which help clean the air and make people happier. e. Although some people worry about losing traditional neighborhoods, modern vertical cities save land and use less energy when they are designed well. A. b-a-c-e-d B. b-e-d-a-c C. b-c-a-e-d D. b-d-a-e-c Read the following passage about Ancient Carbon Released and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22. Deep beneath the Arctic surface lies a frozen time capsule containing vast amounts of organic matter that has remained locked away for millennia; scientists (18)_________. The permafrost, which covers approximately 24% of the Northern Hemisphere's landmass, contains ancient plants, animals, and microbes that never fully decomposed due to the freezing conditions. What makes this frozen repository particularly concerning is the estimated 1,600 billion tons of carbon it holds—nearly twice the amount currently circulating in our atmosphere. Should temperatures continue to climb at current projections, (19)_________. Indigenous communities whose ancestors have inhabited these regions for countless generations are experiencing firsthand the devastating consequences of thawing permafrost, which damages homes, roads, and vital infrastructure built upon what was once stable ground. The knowledge that these communities possess, (20)_________, may provide valuable insights into adaptive strategies that could benefit the wider world. Methane, a greenhouse gas that is twenty-five times more potent than carbon dioxide in trapping heat, bubbles up from thawing lakes and wetlands where it had been safely imprisoned for thousands of years. (21)_________, a process scientists call "positive feedback loop," represents one of the most dangerous climate tipping points we currently face. Were we to immediately halt all human-caused carbon emissions, the permafrost would continue to thaw for decades due to the warming that has already occurred. Satellite monitoring systems that track surface deformation in the Arctic have detected increasing numbers of thermokarst features and coastal erosion accelerating at rates never before documented in human history. The international scientific community must therefore prioritize both mitigation strategies to slow warming and adaptation measures to address the unavoidable consequences of permafrost thaw; (22)_________.
